句中的your work is being done 表明“你正在做作业”，选as 表原因。

2. “I’m going to the post office.” “_______ you’re there, can you get me some stamps?”A. AsB. WhileC. BecauseD. If【陷阱】容易误选A。

(此句中的as 表示原因，意为“因为”、“由于”)请做以下两题，答案均选while，不选as：(1) _______ you are at home alone, please don’t leave the door open.A. WhileB. AsC. BeforeD.

unit4让步状语从句

让步状语从句1.让步状语从句是状语从句中的一种。

一般翻译为“尽管……，即使……”，就是我们日常生活中用的“退一步说……”2.引导让步状语从句的连词主要有：though, although, as, even if, even though, whether…or…;no matter + 疑问词，疑问词加后缀-ever。

（1）though, although表示“虽然，纵然”之意。

这两个连词意思大致相同，在一般情况下可以互换使用。

在口语中，though较常使用，although比though正式，二者都可与yet，still 或nevertheless连用，但不能与but连用。

如：Although/Though he was worn out, (still) he kept on working.虽然他已经精疲力竭了，但仍然继续工作。

Although/Though he is very old, (yet) he is quite strong.他虽然年纪大了，身体还很健壮。

（2）as, though表示“虽然……，即使……”之意。

as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though间或也用于这样的结构中，但although不可以这样用。

如：Object as you may, I’ll go. = Although / Though you may object, I’ll go.纵使你反对，我也要去。

Child as/though he was, he knew what the right thing to do. = Though he was a child, he knew what was the right to do.虽然他是一个孩子，但他知道该做什么。

（3）even if, even though表示“即使……，纵使……”之意。

主从复合句超实用讲解

(6)由Scarcely/hardly...when，no sooner...than 引导时，表示主句动作发生在从句动作一瞬间之前。
2．原因状语从句由 because，as，since 或复合连接词 now that，in that 等
引导。(注意：for 是连词，虽然也可以表示“因为”，但其后所接的是并列句中的一个独立句，而非从句。) 3．地点状语从句由 where，wherever引导。
(7)否定的转移若主句谓语动词为 think，consider，suppose，believe，
expect，guess，imagine 等，且主语为第一人称，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如： I don't think this dress fits you well.我认为这件衣服不适合你穿。
(2)做介词的宾语，例如： Our success depends upon how well we can cooperate
with one another. (3)做形容词的宾语，例如： I am afraid(that) I've made a mistake. (4)it 可以做形式宾语 it 不仅可以做形式主语，还可以做形式宾语，而真正的宾语
7．让步状语从句由 though，although，even if，even though，however，
no matter how/what/who 等引导。注意对让步状语从句的掌握要注意以下几点内容： (1)使用 though，although 时，务必避免与 but 连用，但可以与 yet 连用。 (2)even if，even though 和 as if，as though 不同。后者常常要求使用虚拟语气。
